Definitions

  • the present invention relates to a downhole casing system for performing operations in a wellbore containing well fluid, the downhole casing system comprising at least one casing module comprising a base pipe extending in a longitudinal direction and having a circumference, and a functional assembly mounted over the base pipe to define a casing module flow path between the functional assembly and the base pipe, a main flow path arranged substantially in a centre of the base pipe and extending in a longitudinal direction of the casing system.
  • each screen module comprises individual inflow control means arranged in a base pipe of the screen module, directly under a filtering element.
  • the inflow control means are often comprised by valves or throttles and a sliding sleeve to block and open the inflow control means, respectively.
  • Such screen modules are often sealed off at opposite ends so that fluid, entering the filtering element of one screen module, cannot flow to the subsequent screen module.
  • This configuration of screen modules requires the use of a large number of inflow control means and sliding sleeves in a completion. Using many sliding sleeves in a completion renders the construction, the maintaining and the ongoing operation and control of the completion more expensive.
  • Inflow control means arranged in the base pipe of a screen module will often reduce the flow area or drift diameter of the screen module, thereby reducing flow and the size of the tool that can be used in the well. Further, the flow between the filtering element and the base pipe of a screen module may be of great importance.
  • the production along a single screen module or string of screen often varies considerably with high and low producing areas. It is desirable to provide a flow path between the filtering element and the base pipe, which is as unrestricted and continuous as possible. Multiple separated narrow flow paths along a screen module often result in some flow paths being overloaded, and some having excess capacity.
  • An example of such a tubing string is given in WO 2009/103999 which discloses the features of the preamble of claim 1.
  • a downhole casing system for performing operations in a wellbore containing well fluid
  • the downhole casing system comprising: at least one casing module comprising; a base pipe extending in a longitudinal direction and having a circumference, a functional assembly mounted over the base pipe to define a casing module flow path between the functional assembly and the base pipe, a main flow path arranged substantially in a centre of the base pipe and extending in a longitudinal direction of the casing system, wherein at least a part of the casing module flow path is an annular flow path extending both in the longitudinal direction of the base pipe and continuously around the entire circumference of the base pipe.
  • annular flow path extending continuously around the entire circumference of the base pipe
  • casing module flow path extending in a continuous manner 360 degrees around an outside of the base pipe.
  • a fluid flow along an outer surface of the base pipe is better distributed to optimise the flow of e.g. oil into the main flow path.
  • a continuous flow path around a periphery of the base pipe prevents a restricted or overloaded flow path on one side of the base pipe, e.g. due to blocking scales or high flow volume on the other side, from reducing the overall flow properties of the casing module.
  • the functional assembly may comprise a filtering element, such as a screen, mounted over the base pipe to provide a screen casing module for hindering scales in the well fluid from entering the casing module flow path.
  • a filtering element such as a screen
  • the functional assembly may comprise a perforated outer pipe element mounted over the base pipe to provide an injection casing module for injecting fluid into an annulus surrounding the downhole casing system.

  • the plurality of connecting passages provided in the base pipe may be an alternative or a supplement to the inflow control module.
  • a downhole casing system may further comprise: at least one coupling module extending in a longitudinal direction and adapted to be connected to the casing module and/or another module such as an inflow control module, the coupling module comprising: at least one coupling flow path in fluid communication with the casing module flow path and/or the control module flow path, and a main flow path fluidly connected with the main flow path of the base pipe and/or the main flow path of the inflow control module.
  • internal threaded connections may be provided at the opposite ends of the coupling module.
  • the base pipe may have end sections at which a plurality of supporting structures protrude from an outer surface to provide support for the functional assembly, the supporting structures defining a plurality of casing module flow paths extending in the longitudinal direction.
  • the functional assembly mounted over the base pipe may better withstand the considerable force and tear induced by an iron rough neck when the casing modules, coupling modules and/or inflow control modules are assembled on the drilling rig.
  • External threaded connections may be provided at the opposite ends of the base pipe.
  • an external threaded connection may be provided at one end of the base pipe and an internal threaded connection may be provided at an opposite end of the base pipe.
  • the functional assembly may comprise end rings mounted over the end sections of the base pipe.
  • the end rings may be manufactured from a material providing increased strength and tear resistance to the functional assembly at the end sections
  • the casing modules may better withstand the considerable force and tear induced by an iron rough neck when the casing modules, coupling modules and/or inflow control modules are assembled on the drilling rig.
  • the inflow control module may comprise a sliding sleeve arranged along a surface of the main flow path to control the flow through the connecting passages.

  • each end section 25 a plurality of supporting structures 26 protrude from the outer surface 27 of the base pipe 21 to provide a support for the functional assembly 22.
  • the functional assembly is thereby connected to the base pipe 21 via the supporting structures 26 and thus spans an area of the base pipe located between the end sections 25.
  • the supporting structures 26 divide the encircling casing module flow path 23 into a plurality of separate casing module flow paths each extending over a limited part of the circumference of the base pipe 21 as shown in Fig. 1b .
  • the plurality of separate casing module flow paths is defined by the supporting structures 25 and extend from the encircling casing module flow path towards the ends of the base pipe.
  • the supporting structures 26 strengthen the casing module in the end sections so that when the casing module is connected with another casing module, e.g. by means of an iron rough neck on a drilling rig, the base pipe 21 of the casing module does not collapse.
  • the separate casing module flow paths 23 are open and adapted to be connected to flow paths of abutting modules as described in the following.
